Lingon Labs Close Companion is an ambient finance assistant that works alongside you in Chrome. You select your Gmail, NetSuite, and Google Sheets tabs, and GPT-6 Astra watches for relevant changes and offers help where you’re working. When you accept, Astra investigates invoice evidence across those tabs, checks for existing records, and presents findings with sources. If it encounters a blocker, it asks for help and can continue the same task afterward. You can update or stop it at any time, and you retain control over the final save.
